So, someone decided to bore everyone to death with a 5th-century sea captain's tragic demise from lockjaw. Thanks for the riveting historical tidbit, genius. Who cares about the dude's 2, 500-year-old dental issues We've got more pressing problems than a stiff-necked sailor.
Next, we get a masterclass in soil science and bacterial tourism. Apparently, these Clostridium tetani are having a grand old time vacationing in dirt, dust, and cow poop. Real riveting stuff. And let's not forget the thrilling climax of how these bacteria love to party in your deep puncture wounds. Yippee!
But fear not, gentle viewers! There's a miracle cure: a tiny needle filled with magic potion. Just kidding, it's a vaccine. So exciting. The video basically boils down to Get your shots, folks, or you might turn into a human pretzel.
Honestly, if you're scared of tetanus after watching this snoozefest, you probably deserve it.

Surprised by the fact that you didn't take the time to clear the misconception that is rusty stuff to be able to transmit tetanus.
Truth is rust has nothing to do with it, Clostridium tetani is an anaerobic bacterium, meaning you'll find it in environments with no or few oxygen (such as under the soil, there's absolutely no link with rust.
Long story short: don't put any wounded part in the soil.
On the other hand if you get cut by some rusty piece of metal that has been in the open for a long time there's virtually not risk of contracting tetanus at all, because once again, it's not the rust.

I haven't had that vaccine since i was a child. I just had major abdominal surgery and was never asked about it. 12 weeks after when i was told to establish care with a primary care provider because I haven't had one since my pediatrician I was asked if I needed one. I just said I dont know and that was the end of the visit. I dont think its as big of a issue as this video makes it out.
I have been seen by more doctors in the last 4 months than I have the previous 20 years of my life and only one nurse practitioner even brought it up at the end of a visit.

2: 53 This question crossed my mind and I found the answer:
Q/ If antibiotics are given first, will it make the condition significantly worse since the bacteria will die and release even more toxins
Ans/ This is more relevant in infections caused by endotoxin-producing bacteria, like Escherichia coli in sepsis, where rapid bacterial lysis can release endotoxins. However, the tetanus toxin is an exotoxin, which is actively secreted by the bacteria rather than released in large amounts upon bacterial death.

I live in a village in India, the area is definitely a lot developed then the remote villages but over here the tetnus vaccine access is pretty good, it just cost you 13 cents or so. But the problem definitely is about awareness. Unlike my parents and teachers who taught me about what you should do when you have a chance of infection many don't have the privilege of this common yet exclusive knowledge.

I stepped on a rusty nail on a board in the woods as a kid. A pretty big one aswell, went straight through my rubber boots almost through my whole foot. Luckily i think i didn't get any tetanus, since i don't remember any prolonged agony (outside of walking normally lol. However what i do remember, and will never forget, is my moms face when i explanied what i had done. Rushed me to medical aid.

After met with a minor bike accident, one of my acquaintance had some small cuts in his leg. but he didnt mind it. next day he got lot of swelling but decided to not treat but took bus to go to his home. The second day he admitted in hospital for he couldnt move his leg. Third day he had to sacrifice his one entire leg as the infection mixed in blood stream. Fourth day he died.

i always thought tetanus by RUST. i remember watching a movie a long time ago where they are one an island where everyone age super fast. the protagonist used a rusty fork to impale a mad man who immediately died. the special effects showed red markings on his hands as if rust travelled up his blood vessels. i really thought its was rust killing him.
reply

There are far less than 50 cases of this per year. Lets do that math. 345, 000, 000 people in the usa. Times 365 days in a year equals. well you have a better chance of being killed by a serial killer, a hippo, a falling meteor, assualted by a bigfoot. Kisses by a unicorn. Or you literally have a better chance of being abducted by aliens.

Although the tetanus vaccine prevents this deadly disease, and I thank them for this, But it is not right to make this vaccine mandatory for children, considering the non-contagious nature of this disease. I remember that when I was enrolled in school, they did not accept me because I had not had the tetanus vaccine and I had to be injected.
reply

My grandpa was a medical doctor and told me how he once diagnosed an infant with tetanus. Nobody else wanted to make the diagnosis because the prognosis would be so bad. The family were immigrants; they hadn't been vaccinated, and the father had tied off the umbilical cord with shoe laces. Unfortunately the infant passed away.
reply

Imagine the endless suffering you’re caught in during those 6 days. But still, I’d rather have this than rabies. And I’d rather get the hangman before my windpipe does me anyway, but I guess that even in those days there were people who sometimes recouped, so you were caught in this horrid situation
reply

I once stepped on a rusty nail, but must had all the luck on the world, because i felt it on the shoe sole and didn't got injured. I hate Tetanus vaccinations. Last one i had 12 years ago and didn't even went to get the second vaccination, because my arm was hurting for more than 2 weeks from the first one.
reply

Thank you for this video & the one about Alzheimer’s disease! As I’m getting older, I realize how important our health is. Please keep making videos about health, illness, & treatment. Complimentary and alternative therapy topic (massage, acupuncture, herbal remedies, etc) would also be great!
reply

When I was a kid, Mom said that the flakey texture of rust gave the bacteria shelter. And the depth of a puncture wound like from a nail was harder to clean out and that was why stepping on rusty nails could give you tetanus. Thankfully I never got that when I did get a nail in my foot!
reply

That’s kind of scary to think that you can get the tiniest cut from rusted metal and the bacteria could still come into your skin or inside of you and I thought that tetanus only makes you extremely sick and not cause random spazams from the muscles and other things which is crazy insane.
reply

I’ve survived getting punctured by two nails in the thigh before because of my cousin that he accidentally kicked a piece of wood that had two rusty nails sticking out the end and the thing that scared me so much more than the two nails going into my thigh was getting tetanus
reply

Hmm now i see that whenever i got injured or was in an accident on Motorbike i had to go to hospital to get injection at that time i use to wonder why people want me to get injected about scratches.
I knew about tetanus but i didn't know that it lie on the soil

reply

In my country vaccine is must have once in 10 years now. I had my last in 2019. and next date for revaccination is 2029. but in case of my parents and in their time, that wasn't the case. They did not need to vaccinate once in 10 years but now we simply must.
reply

Tetinus isn't related to rust after all! It's just a correlation about cutting your skin near places where the bacteria hangs out!
Add that to the list of incorrect public knowledge that will probably never be fixed. But thanks for spreading the word.
